Doc Blevins is an aging blues and jazz guitarist, content with a steady gig at a popular pasta house and a long-time girlfriend. After a late-night jam session, a mysterious black van whisks Blevins away. He then embarks on a tuneful adventure and a chance to revive a stalled musical career. Traveling the Southwest, Doc finds himself headlining club concerts on a boozy road trip that includes adoring groupies, passionate music, and a bar brawl here and there - all standard fare for life on the club circuit. Along the way, he gets schooled on the hard business side of the music trade, on the fine art of public relations, and on the trade-offs of road-trip romance. And Doc learns that a second chance at fame comes with certain costs, and dues-paying does not necessarily respect age and wisdom.
